In <vadefs.h> you'll find the following definition for the macro _ADDRESSOF(v) in VS2019:
#ifdef __cplusplus
#define _ADDRESSOF(v) (&const_cast<char&>(reinterpret_cast<const volatile char&>(v)))
#else
#define _ADDRESSOF(v) (&(v))
#endif
I'd like to understand the first definition above, when __cplusplus is defined. Why does it work?
